Wow, a husband putting his wife as beneficiary and giving her access to his bank account; That is very suspicious!!!
Were you born in 1700 ?
First of all she claims to be his exwife and second of all she also claimed that he had previously told her about his plans, something that a grand jury is currently deciding if they will charge her with.
I would say that her ties to this case definitely warrant knowing where she is at this point in the investigation.
